Neither side made provisions for large numbers of prisoners. Guarding prisoners was a secondary consideration to winning the war.

Parole violations do not have a limit. A violator can be picked up and returned to prison to finish their sentence at any time.
Every state has a parole board, although it may not be called that. The parole board reviews the cases of prisoners coming up for parole, and also hears/reads the petitions of citizens favoring or opposed to parole. By calling the parole board in your state, you can find out the procedures for filing such a petition, and where it should be sent. You may be able to appear before the parole board to make your feelings known in person.
